PeachParts Mercedes-Benz Forum - '86 560SL compressor won't engage - just happened after some troubleshooting!

I was having a problem with no AC coming out of the center vents - common problem and one that I had previously fixed on this car by replacing the Center/Defrost vacuum pod. So, today I took the radio out and the AC/Heater control panel, the glove box and pulled out my vacuum pump. I got the center vents working, but I think I have a vacuum leak somewhere - NOT in the new pod I replaced, but a slow leak in the one that's in the heater box...

Anyway, after I do all of my troubleshooting, I put things together and now the AC compressor won't engage at all. It was working fine just earlier today - before I did all of this "fixing"!

Any suggestions? I suppose it's possible that it's a coincidence...but could I have accidentally disconnected something?
